VPen

A class to specify the pen used to draw lines and shapes.

Synopsis

Pens are used to draw lines and the outlines of shapes. Pens have several attributes, including color, width, and style.

vPen(unsigned int r = 0, unsigned int g = 0, unsigned int b = 0, int width = 1, int style = vSolid)

The constructor for a pen allows you to specify the pen's color, width, and style. The default will construct a solid black pen of width 1.

int operator ==, !

You can use the operators == and != for comparisons.

vColor GetColor()

This method returns the current color of the pen as a vColor object.

int GetStyle()

This method returns the current style of the pen.

void GetWidth()

This gets the width of the line the pen will draw.

void SetColor(vColor& c)

You can use this method to set the pen color by passing in a vColor object.

void SetStyle(int style)

This method is used to change the style of a pen. Styles include:

vSolid: The pen draws a solid line.
vTransparent: The pen is transparent. A transparent pen can be used to avoid drawing borders around shapes. When drawing text, a transparent pen draws the text over the existing background.
vDash: The pen draws a dashed line.
vDot: The pen draws a dotted line.
vDashDot: The pen draws an alternating dash and dotted line.

void SetWidth(int width): This sets the width of the line the pen will draw.
